But more than anything, Carson’s speech — like many of the remarks Tuesday night, despite the evening’s theme of “making America work again” — was a repudiation of Hillary Clinton. In particular, Carson latched onto Clinton’s admiration for Saul Alinsky, the community organizer who’s much loathed by the right.

“One of the things that I have learned about Hillary Clinton is that one of her heroes, her mentors, was Saul Alinsky. Her senior thesis was about Saul Alinsky,” Carson said. “This was someone she greatly admired and that affected all of her philosophy subsequently.”

Carson went on to ask the crowd, “Are we willing to elect someone as president who has as their role model somebody who acknowledges Lucifer?”

As Vox explains, Carson is referring to the widespread, and incorrect, notion that Alinsky dedicated his book Rules for Radicals to “Lucifer.” In fact, Alinsky dedicated the book to his wife, Irene, but acknowledged Lucifer as “the very first radical,” in a tongue-in-cheek fashion.

Earlier in the day Tuesday, Carson responded to a reporter who asked him what he planned to say in his speech, “Only God knows the answer to that.”
